CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/751,172, filed on Jan. 23, 2020, which is a continuation of International Application No. PCT/CN2017/098319, filed on Aug. 21, 2017, the contents of each of which are incorporated herein by reference to its entirety.

TECHNICAL FIELD

This application generally relates to an online carpool transportation service, and in particular, a recommendation of a pickup location for a carpool service requestor.

BACKGROUND

A carpool transportation service refers to an arrangement that combines two or more transportation services into a new transportation service. The carpool transportation service may improve the traffic capacity. In existing systems and methods for carpool, a driver may pick up a passenger at a location determined by the passenger, which may cause some problems such as inefficiency and a bad user experience. For example, the location may be inconvenient for the driver. As another example, if the driver is unfamiliar with the location, the driver has to ask the passenger through a smartphone. Therefore, it is desirable to provide systems and methods for recommending a pickup location to a passenger to improve the efficiency and the user experience.

One or more of the above positioning systems may be used interchangeably in the present disclosure.

An aspect of the present disclosure relates to online systems and methods for recommending a pickup location to a passenger that requests a carpool transportation service. In some embodiments, when a server of an online on-demand transportation service platform receives a request for a transportation service from a passenger, or the server detects that the passenger intends to request a transportation service, the server may determine a pickup location for the passenger to get on board. The server may obtain a plurality of candidate locations close to the passenger (e.g., the plurality of candidate locations may be within 200 meters from the passenger). The server may determine the plurality of candidate locations in advance. For each candidate location, the server may determine a probability of being the pickup location of the passenger. The server may determine the probability based on a score of the user experience of walking from the origin to the candidate location, a score of the user experience of driving from the candidate location to the destination, and a probability of finding a shareable transportation service to combine with the transportation service in the candidate location. The server may select the candidate location with the greatest probability of being the pickup location of the passenger as the pickup location and transmit the pickup location to the passenger's smartphone to notify the passenger of the pickup location.

It should be noted that online on-demand transportation service, such as online carpool service, is a new form of service rooted only in post-Internet era. It provides technical solutions to users and service providers that could raise only in post-Internet era. In the pre-Internet era, when a user hails a taxi on the street, the taxi request and acceptance occur only between the passenger and one taxi driver that sees the passenger. If the passenger hails a taxi through a telephone call, the service request and acceptance may occur only between the passenger and one service provider (e.g., one taxi company or agent). If a driver wants to provider a carpool service, the driver has to ask a passenger face to face and determine whether the carpool service is possible to be provided to the passenger by experience of the driver. Online carpool service, however, obtains transaction requests and finds combinable transaction requests in real-time and automatically. The carpool service also allows a user of the service to real-time and automatic distribute a service request to a vast number of individual service providers (e.g., taxi) distance away from the user and allows a plurality of service providers to respond to the service request simultaneously and in real-time. Therefore, through Internet, the online on-demand transportation systems may provide a much more efficient transaction platform for the users and the service providers that may never met in a traditional pre-Internet transportation service system.

FIG. 1 is a schematic diagram of an exemplary online on-demand transportation service system 100 according to some embodiments of the present disclosure. The online on-demand transportation service system 100 may include a server 110, a network 120, a requestor terminal 130, a provider terminal 140, and a storage 150. The server 110 may include a processing engine 112.

In some embodiments, the server 110 may manage carpool transportation services for service requestors and service providers. In some embodiments, the transportation service may be a service of taking a subject from one location to another location using a vehicle. The subject may include passengers and/or goods. For example, the transportation service may be a taxi service or a delivery service. The vehicle of the transportation systems may include a taxi, a private car, a hitch, a bus, a bike, an electric bicycle, a tricycle, a motorcycle, a train, a bullet train, a high speed rail, a subway, a vessel, an aircraft, a spaceship, a hot-air balloon, a driverless vehicle, or the like, or any combination thereof. The carpool transportation service may refer to an arrangement that combines two or more transportation services into anew transportation service. For example, the server 110 may combine two taxi services into a new transportation service. As another example, the server 110 may combine two delivery services into a new transportation services. As still another example, the server 110 may combine a taxi service and a delivery service into a new transportation service.

In some embodiments, the transportation service may be a real-time transportation service. A real-time transportation service may be a service that the requestor wishes to receive the transportation service at the present moment or at a defined time reasonably close to the present moment for an ordinary person in the art, so that a service provider is required to depart immediately or substantially immediately after the server 110 receives the service request. For example, a taxi service may be a real-time service if the defined time is shorter than a threshold value, such as 1 minute, 5 minutes, or 10 minutes.

In some embodiments, the transportation service may be a service that needs to make an appointment, which refers to a service that the requestor wishes to receive the service at a time reasonably long from the present moment for the ordinary person in the art, so that a service provider is not required to depart immediately or substantially immediately after the server 110 receives the service request. For example, a passenger may need to reserve a taxi service if the time between the current time and the service time is longer than a threshold value, such as 20 minutes, 2 hours, or 1 day.

The time threshold may be a fixed time period or may be adjustable depending on different situations. For example, in rush hours (e.g., 7:00 am-9:00 am), the time threshold may be relatively long (e.g., 10 minutes) because it may take a service provider longer time to arrive the service requestor's location; whereas in other hours (e.g., 10:00 am-12:00 am), the time threshold may be relatively short (e.g., 5 minutes) as the service provider may need shorter time to pick-up a service requestor.

In some embodiments, the server 110 may be a single server or a server group. The server group may be centralized, or distributed (e.g., the server 110 may be a distributed system). In some embodiments, the server 110 may be local or remote. For example, the server 110 may access information and/or data stored in the requestor terminal 130, the provider terminal 140, and/or the storage 150 via the network 120. As another example, the server 110 may be directly connected to the requestor terminal 130, the provider terminal 140, and/or the storage 150 to access stored information and/or data. In some embodiments, the server 110 may be implemented on a cloud platform. Merely by way of example, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, or the like, or any combination thereof. In some embodiments, the server 110 may be implemented on a computing device 200 having one or more components illustrated in FIG. 2 in the present disclosure.

In some embodiments, the server 110 may include a processing engine 112. The processing engine 112 may process information and/or data relating to the service request to perform one or more functions described in the present disclosure. For example, the processing engine 112 may determine one or more pickup locations and transmit the one or more pickup locations to the requestor terminal 130. In some embodiments, the processing engine 112 may include one or more processing engines (e.g., single-core processing engine(s) or multi-core processor(s)). Merely byway of example, the processing engine 112 may include one or more hardware processors, such as a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction-set processor (ASIP), a graphics processing unit (GPU), a physics processing unit (PPU), a digital signal processor (DSP), a field-programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction-set computer (RISC), a microprocessor, or the like, or any combination thereof.

The network 120 may facilitate the exchange of information and/or data. In some embodiments, one or more components of the online on-demand transportation service system 100 (e.g., the server 110, the requestor terminal 130, the provider terminal 140, and the storage 150) may transmit information and/or data to another component(s) of the online on-demand transportation service system 100 via the network 120. For example, the server 110 may obtain/acquire a service request from the requestor terminal 130 via the network 120. In some embodiments, the network 120 may be any type of wired or wireless network, or a combination thereof. Merely by way of example, the network 120 may include a cable network, a wireline network, an optical fiber network, a telecommunications network, an intranet, the Internet, a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a metropolitan area network (MAN), a wide area network (WAN), a public telephone switched network (PSTN), a Bluetooth network, a ZigBee network, a near field communication (NFC) network, or the like, or any combination thereof. In some embodiments, the network 120 may include one or more network access points. For example, the network 120 may include wired or wireless network access points such as base stations and/or internet exchange points 120-1, 120-2, . . . , through which one or more components of the online on-demand transportation service system 100 may be connected to the network 120 to exchange data and/or information.

In some embodiments, a requestor may be a user of the requestor terminal 130. In some embodiments, the user of the requestor terminal 130 may be someone other than the requestor. For example, user A of the requestor terminal 130 may use the requestor terminal 130 to transmit a service request for user B, or receive service and/or information or instructions from the server 110. In some embodiments, a provider may be a user of the provider terminal 140. In some embodiments, the user of the provider terminal 140 may be someone other than the provider. For example, a user C of the provider terminal 140 may user the provider terminal 140 to receive a service request for a user D, and/or information or instructions from the server 110. In some embodiments, “requestor” and “requestor terminal” may be used interchangeably, and “provider” and “provider terminal” may be used interchangeably.

In some embodiments, any other suitable component, including but not limited to a system bus or a controller (not shown), may also be included in the mobile device 300. In some embodiments, a mobile operating system 370 (e.g., iOS™, Android™, Windows Phone™) and one or more applications 380 may be loaded into the memory 360 from the storage 390 in order to be executed by the CPU 340. The applications 380 may include a browser or any other suitable mobile apps for receiving and rendering information relating to an online carpool transportation service or other information from the server 110, and transmitting information relating to an online carpool transportation service or other information to the server 110. User interactions with the information stream may be achieved via the I/O 350 and provided to the server 110 and/or other components of the online on-demand transportation service system 100 via the network 120.

FIG. 4 is a schematic diagram illustrating an exemplary processing engine 112 according to some embodiments of the present disclosure. As shown in FIG. 4 , the processing engine 112 may include a communication module 410, a service information determining module 420, a candidate location determining module 430, an index determining module 440, and a pickup location determining module 450. The communication module 410 may establish communication with one or more components of the online on-demand transportation service system 100 (e.g., the requestor terminal 130, the provider terminal 140, and the storage 150). For example, the communication module 410 may receive a request or an intention for a transportation service from a service requestor. As another example, the communication module 410 may transmit one or more pickup locations to a service requestor.

The service information determining module 420 may determine an origin location of the transportation service and/or a destination of the transportation service. In some embodiments, the request or the intention received by the communication module 410 may include the origin location of the transportation service and/or the destination of the transportation service. The service information determining module 420 may determine the origin location and the destination based on the request or the intention.

The candidate location determining module 430 may obtain a plurality of predetermined locations and/or determine one or more candidate locations based on the origin location and the predetermined locations. In some embodiments, the server 110 may determine the plurality of predetermined locations in an area (e.g., the city of Beijing) in advance. The predetermined locations may be used to determine one or more pickup locations for a specific transportation service. The predetermined locations may be stored in the storage 150 or a storage medium (e.g., the disk 270, the ROM 230, or the RAM 240) of the server 110. In some embodiments, the one or more candidate locations may be one or more the predetermined locations within a predetermined distance (e.g., 500 meters) from the origin. The predetermined distance may be a fixed distance or may be adjustable depending on different situations. The candidate location determining module 430 may access the storage 150 and/or the storage medium to obtain the predetermined locations to determine the one or more candidate locations.

The index determining module 440 may determine a matching index value of at least one of the candidate locations based on the origin location and/or the destination. The matching index value of a candidate location may be the probability of the candidate location being a pickup location of the transportation service.

The pickup location determining module 450 may determine one or more pickup locations based on the matching index values.

The modules in the processing engine 112 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined as a single module, and any one of the modules may be divided into two or more units. For example, the communication module 410 may be divided into two units. The first unit may be configured to receive a request or an intention from a service requestor. The second unit may be configured to transmit one or more pickup locations to the service requestor.

It should be noted that the above description is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, the processing engine 112 may further include a storage module (not shown in FIG. 4 ). The storage module may be configured to store data generated during any process performed by any component of in the processing engine 112 (e.g., the communication module 410, the service information determining module 420, the candidate location determining module 430, the index determining module 440, or the pickup location determining module 450). As another example, each of components of the processing engine 112 may include a storage device. Additionally or alternatively, the components of the processing engine 112 may share a common storage device.

One of ordinary skill in the art would understand that when an element of the online on-demand transportation service system 100 performs, the element may perform through electrical signals (e.g., current) and/or electromagnetic signals. For example, when a requestor terminal 130 transmits out a service request to the server 110, a processor of the requestor terminal 130 may generate an electrical signal encoding the request. The processor of the requestor terminal 130 may then transmit the electrical signal to an output port. If the requestor terminal 130 communicates with the server 110 via a wired network, the output port may be physically connected to a cable, which further transmit the electrical signal to an input port of the server 110. If the requestor terminal 130 communicates with the server 110 via a wireless network, the output port of the requestor terminal 130 may be one or more antennas, which convert the electrical signal to electromagnetic signal. Similarly, a provider terminal 140 may receive an instruction and/or service request from the server 110 via electrical signal or electromagnet signals. Within an electronic device, such as the requestor terminal 130, the provider terminal 140, and/or the server 110, when a processor thereof processes an instruction, transmits out an instruction, and/or performs an action, the instruction and/or action is conducted via electrical signals. For example, when the processor retrieves or saves data from a storage medium, it may transmit out electrical signals to a read/write device of the storage medium, which may read or write structured data in the storage medium. The structured data may be transmitted to the processor in the form of electrical signals via a bus of the electronic device. Here, an electrical signal may refer to one electrical signal, a series of electrical signals, and/or a plurality of discrete electrical signals.

The communication module 410 may receive a request or an intention for a transportation service from a service requestor. In some embodiments, the requestor terminal 130 of the service requestor (e.g., a passenger's smartphone) may install an application for requesting a transportation service. Through an interface of the application, the requestor terminal 130 may establish a connection and communicate with the online on-demand transportation service system 100. In some embodiments, the service requestor may input an origin location and a destination of the transportation service, and transmit out a request including the origin location and the destination of the transportation service to the communication module 410 via, for example, the network 120. In some embodiments, the application may direct the requestor terminal 130 to constantly monitoring inputs from the service requestor and transmit the input to the communication module 410. As a result, when the service requestor inputs part of the information of the transportation service, such as a destination, the communication module 410 may receive enough information in real-time or substantially real-time to determine an intention of the service requestor. For example, when the service requestor inputs an origin location and a destination of the transportation service and before transmitting out the transportation service request to the communication module 410, the communication module 410 may receive and/or detect the origin location and the destination from the service requestor in real-time or substantially real-time, and determine that the service requestor intends to request the transportation service before receiving a request for the transportation service from the service requestor.

In some embodiments, the communication module 410 may receive service signals from the requestor terminal 130. The service signals may include a first portion of structured data encoding the request or the intention for the transportation service, a second portion of the structured data encoding the origin location of the transportation service, and a third portion of the structured data encoding the destination of the transportation service.

The service information determining module 420 may determine an origin location of the transportation service and a destination of the transportation service. In some embodiments, the request or the intention received by the communication module 410 may include the origin location of the transportation service and/or the destination of the transportation service. The service information determining module 420 may determine the origin location and the destination based on the request or the intention.

The candidate location determining module 430 may obtain a plurality of predetermined locations. In some embodiments, the candidate location determining module 430 may determine the plurality of predetermined locations in an area (e.g., the city of Beijing) in advance. The predetermined locations may be used to determine one or more pickup locations for a specific transportation service. The predetermined locations may be stored in the storage 150 or a storage medium (e.g., the disk 270, the ROM 230, or the RAM 240) of the processing engine 112. The candidate location determining module 430 may access the storage 150 and/or the storage medium to obtain the predetermined locations.

In some embodiments, the candidate location determining module 430 may transmit access signals to access the storage medium to read the plurality of predetermined locations. For example, the candidate location determining module 430 may transmit the access signals to access the storage 150 to read the plurality of predetermined locations.

The candidate location determining module 430 may determine one or more candidate locations based on the origin location and the plurality of predetermined locations. The candidate location determining module 430 may select one or more predetermined locations that are within a predetermined distance (e.g., 500 meters) from the origin location as the candidate location(s). The predetermined distance may be a fixed distance or may be adjustable depending on different situations. For example, if the origin location is in a downtown area (e.g., the Xicheng district in Beijing), the predetermined distance may be relatively short (e.g., 400 meters) because the density of the predetermined locations there may be higher; whereas if the origin location is in a suburban area (e.g., the Changping district in Beijing), the predetermined distance may be relatively long (e.g., 1 kilometer) as the density of the predetermined locations there may be lower.

The index determining module 440 may determine matching index values of the candidate locations based on the origin location and/or the destination. In some embodiments, the index determining module 440 may determine a matching index value for each candidate location. The matching index value of a candidate location may be the probability of the candidate location being a pickup location of the transportation service. The greater the matching index value is, the more suitable the candidate location is to be a pickup location for the transportation service. The matching index value may be in the form of a score, a percentage, a star level, or any suitable form.

In some embodiments, the index determining module 440 may determine the matching index value based on a walking cost, a convenience index, or a combination probability (e.g., as will be described in detail in connection with FIG. 6 ), or a combination thereof. The walking cost be a measurement associated with walking from the origin location to the candidate location. The convenience index may be a measurement associated with driving from the candidate location to the destination. The combination probability may be a probability of finding one or more shareable transportation services in the candidate location to combine with the transportation service.

The pickup location determining module 450 may determine one or more pickup locations based on the matching index values. In some embodiments, the pickup location determining module 450 may rank the matching index values in ascending order or descending order. In some embodiments, the pickup location determining module 450 may determine one pickup location from the candidate locations based on the matching index values. For example, the pickup location determining module 450 may determine the candidate location having the greatest matching index value as the pickup location of the transportation service. In some embodiments, the pickup location determining module 450 may determine more than one pickup location. For example, the pickup location determining module 450 may determine the top three candidate locations as the pickup locations based on the matching index values.

The communication module 410 may transmit the one or more pickup locations to the service requestor and/or the service provider. In some embodiments, if the pickup location determining module 450 determines one pickup location, the communication module 410 may transmit the pickup location to the service requestor. After receiving the pickup location, the application installed in the requestor terminal 130 of the service requestor (e.g., a smartphone of a passenger) may provide an interface to notify the passenger of the pickup location in the way of text, sound, picture, video, or the like, or any combination thereof. For example, the interface of the application may display a text showing “Please get on board at East Gate of Renmin University.” Alternatively or additionally, the communication module 410 may transmit the pickup location to a service provider that provides the transportation service to the service requestor.

In some embodiments, if the pickup location determining module 450 determines more than one pickup location, the communication module 410 may transmit the more than one pickup location to the service requestor. The service requestor may select one from the more than one pickup location. After receiving the more than one pickup location, the application installed in the requestor terminal 130 of the service requestor (e.g., a smartphone of a passenger) may provide an interface to notify the passenger of the more than one pickup location in a way of text, sound, picture, video, or the like, or any combination thereof. For example, the interface of the application may display a list of the more than one pickup location. In the list, the more than one pickup locations may be arranged in ascending order, descending order, or random order. The passenger may select one pickup location from the list. After receiving the instruction of selecting one from the one or more pickup locations, the requestor terminal 130 may transmit the selected pickup location to the processing engine 112. Alternatively or additionally, after receiving the selected pickup location from the requestor terminal 130, the communication module 410 may transmit the selected pickup location to the service provider who provides the transportation service to the service requestor.

In some embodiments, the communication module 410 may transmit location signals encoding the one or more pickup locations to the requestor terminal 130.

In some embodiments, the processing engine 112 may determine whether the carpool transportation service is available for the area in which the origin location locates. The pickup location determining module 450 may determine one or more pickup locations for the service requestor in response to the determination that the carpool transportation service is available in the area. In response to the determination that the carpool transportation service is available for the area that the origin location locates in, the communication module 410 may transmit a message to the requestor terminal 130 to notify the service requestor of the determination.

The index determining module 440 may determine a walking cost of a candidate location. The walking cost may be a measurement associated with walking from the origin location to the candidate location. In some embodiments, the index determining module 440 may determine a score of the walking cost. The greater the score of the walking cost is, the better the user experience of walking from the origin location to the candidate location is. In some embodiments, the index determining module 440 may determine the walking cost based on the walking distance between the origin location and the candidate location, the estimated walking time between the origin location and the candidate location, the direct distance between the origin location and the candidate location, or the number of historical requests of which pickup locations are the candidate location (e.g., as described in detail in connection with FIG. 7 ), or a combination thereof.

The index determining module 440 may determine a convenience index of the candidate location. The convenience index may be a measurement associated with driving from the candidate location to the destination by the service provider. In some embodiments, the index determining module 440 may determine a score of the convenience index. The greater the score of the convenience index is, the better the user experience of driving from the candidate location to the destination is. In some embodiments, the index determining module 440 may determine the convenience index based on a driving distance between the candidate location and the destination, the estimated driving time between the candidate location and the destination, an angle between a direction from the origin location to the candidate location, a direction from the origin location to the destination (e.g., as will be described in detail in connection with FIG. 8 ), or a combination thereof.

The index determining module 440 may determine a combination probability of the candidate location. The combination probability may be a probability of finding one or more shareable transportation services in the candidate location to combine with the transportation service. A shareable transportation service may satisfy at least three conditions: the pickup location of the shareable transportation service is the candidate location; a service requestor of the sharable transportation service has not departed from the candidate location (e.g., the service requestor of the shareable transportation service is on the way of going to the candidate location, or the service requestor of the shareable transportation service is waiting for a driver at the candidate location); the destination of the shareable transportation is related to the destination of the transportation service (e.g., the destination of the shareable transportation is on a driving route of the transportation service, the destination of the transportation service is on a driving route of the shareable transportation service, or the destination of the shareable transportation is within a distance from the destination of the transportation service). In some embodiments, the index determining module 440 may determine the combination probability based on the number of shareable transportation services in the candidate location and a carpool capacity. The carpool capacity may be the maximum number of passengers in a vehicle at the same time. The carpool capacity may be a fixed value or may be adjustable depending on different situations. For example, in rush hours (e.g., 7:00 am-9:00 am), the carpool capacity may be relatively great (e.g., 4 passengers) because the demand for service providers may exceed the supply; whereas in other hours (e.g., 10:00 am-12:00 am), the carpool capacity may be relatively small (e.g., 2 passengers) as the supply of service providers may exceed the demand or there may be a balance between demand and supply of service providers.

For the purpose of illustration, the determination of the combination probability may be described using an example below. It should be noted that the determination of the combination probability described below is merely provided for illustration and not intended to limit the scope of the present disclosure. For example, suppose that the number of passengers of a transportation service may be 1. The index determining module 440 may determine that the carpool capacity is 2 passengers. The index determining module 440 may determine three candidate locations (e.g., location A, location B, and location C). The index determining module 440 may determine that there is no shareable transportation service in location A, there is 1 shareable transportation service in location B, and there are 2 shareable transportation services in location A. The index determining module 440 may determine that the combination probability of location B is the greatest and the combination probability of location A is the least.

In some embodiments, for a condition that there is no shareable transportation service in all of the candidate locations, the index determining module 440 may determine the combination probability based on historical requests. For example, the index determining module 440 may access the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240) to obtain the number of historical shareable transportation services associated with the time point when the communication module 410 receives the request or the intention for the transportation service from the service requestor and the candidate location. The historical shareable transportation service may satisfy at least three conditions: the pickup location of the historical shareable transportation service is the candidate location; the historical shareable transportation service ended (e.g., the historical shareable transportation service may be cancelled or finished); the destination of the historical shareable transportation is related to the destination of the transportation service (e.g., the destination of the historical shareable transportation is on a driving route of the transportation service, the destination of the transportation service is on a driving route of the historical shareable transportation service, or the destination of the historical shareable transportation is within a distance from the destination of the transportation service). For example, the communication module 410 receives the request or the intention for the transportation service from the service requestor at 9:10 am. The index determining module 440 may obtain historical shareable transportation services of which the request times are in a range from, for example, 9:05 am-9:15 am of every one of the past 5 days.

In some embodiments, the index determining module 440 may determine a score of the combination probability. The greater the score of the combination probability is, the greater the combination probability is, and the more possible it is to find a shareable transportation service in the candidate location to combine with the transportation service.

The index determining module 440 may determine a matching index value based on the walking cost, the convenience index, and the combination probability. The index determining module 440 may determine weights for the walking cost, the convenience index, and the combination probability. In some embodiments, the index determining module 440 may determine the matching index value by determining a weighted average of the walking cost, the convenience index, and the combination probability.

The index determining module 440 may determine a walking route from the origin location to the candidate location.

The index determining module 440 may determine a walking distance based on the walking route. In some embodiments, the walking distance may be the length of the walking route.

The index determining module 440 may determine an estimated walking time based on the walking route. In some embodiments, the index determining module 440 may determine the estimated walking time based on the walking distance, walking speed, condition of the walking route, or the like, or any combination thereof.

In some embodiments, the walking speed may be a fixed speed (e.g., 4 km/h) or may be adjustable depending on different situations. For example, for passengers over 60 years old, the walking speed may be relatively slow (e.g., 3 km/h); for passengers from 20 to 60 years old, the walking speed may be relatively fast (e.g., 4.5 km/h). In some embodiments, the service requestor may input his/her basic information (e.g., a name, a phone number, an age) when the service requestor first uses the application installed in the requestor terminal 130 (e.g., a smartphone of the service requestor) to request a transportation service. The requestor terminal 130 may transmit the basic information to the index determining module 440. After receiving the basic information, the server 110 may store the basic information in the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240). When determining the walking speed, the index determining module 440 may access the storage 150 or the storage medium to obtain the basic information of the service requestor and determine the walking speed based on the basic information. In some embodiments, the requestor terminal 130 may determine the walking speed of the service requestor using the positioning technology in the requestor terminal 130 and transmit the walking speed to the index determining module 440 in real time. The condition of the walking route may include the weather, information on events (e.g., a traffic accident, a concert), or the like, or any combination thereof.

The index determining module 440 may determine a direct distance from the origin location to the candidate location.

The index determining module 440 may determine the number of historical requests associated with the candidate location. The number of requests associated with the candidate location may refer to the number of historical requests in a time period (e.g., in the past one month from the time point when the processing engine 112 receives the service request or the intention of the transportation service) of which the pickup locations are the candidate location.

The index determining module 440 may determine a walking cost based on the walking distance, the estimated walking time, the direct distance or the quantity of historical requests associated with the candidate location. In some embodiments, the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location may correspond to a score, respectively. The shorter the walking distance is, the higher the score determined by the index determining module 440 for the walking distance is. The shorter the estimated walking time is, the higher the score determined by the index determining module 440 for the estimated walking time is. The shorter the direct distance is, the higher the score determined by the index determining module 440 for the direct distance is. The greater the number of historical requests associated with the candidate location is, the higher the score determined by the index determining module 440 for the number of historical requests associated with the candidate location is. In some embodiments, the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location may correspond to a weight, respectively. The index determining module 440 may determine the walking cost by determining a weighted average of the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location.

The index determining module 440 may determine a driving route from the candidate location to the destination.

The index determining module 440 may determine a driving distance based on the driving route. The driving distance may refer to the length of the driving route.

The index determining module 440 may determine an estimated driving time based on the driving route. In some embodiments, the index determining module 440 may determine the estimated driving time based on the driving distance, driving speed, the condition of the driving route, or the like, or any combination thereof.

In some embodiments, the driving speed may be a fixed speed (e.g., 40 km/h), or may be adjustable depending on different situations. For example, for a high configuration vehicle (e.g., a BMW™), the driving speed may be relatively great (e.g., 45 km/h); for a low configuration vehicle (e.g., an Alto™), the driving speed may be relatively small (e.g., 35 km/h).

For a condition that the processing engine 112 has allocated a service provider to the service requester, the index determining module 440 may determine the driving speed based on the vehicle of the service provider. In some embodiments, the service provider may input his/her basic information (e.g., a name, a phone number, a vehicle type, a vehicle plate number) when the service provider first uses the application installed in the provider terminal 140 (e.g., a smartphone of the service provider) to provide a transportation service. The provider terminal 140 may transmit the basic information of the service provider to the processing engine 112. After receiving the basic information of the service provider, the processing engine 112 may store the basic information in the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240). When determining the driving speed, the index determining module 440 may access the storage 150 or the storage medium to obtain the basic information of the service provider and determine the driving speed based on the basic information of the service provider. Alternatively or additionally, the provider terminal 140 may determine the driving speed of the vehicle using the positioning technology in the provider terminal 140 and transmit the driving speed to the index determining module 440 in real time.

For a condition that the processing engine 112 has not allocated a service provider to the service requestor, the index determining module 440 may determine the driving speed based on the default of the processing engine 112 (e.g., 40 km/h).

The condition of the driving route may include the number of vehicles on the driving route, the weather, information on events (e.g., a traffic accident, a concert), or the like, or any combination thereof.

The index determining module 440 may determine the first direction from the origin location to the destination and a second direction from the origin location to the candidate location.

The index determining module 440 may determine an angle between the first direction and the second direction. In some embodiments, the index determining module 440 may determine the angle between the first direction and the second direction in order to determine whether the candidate location and the destination are in two opposite directions of the origin location. If the index determining module 440 determines that the angle is 0°, the candidate location and the destination may be in a same direction of the origin location. If the index determining module 440 determines that the angle is 180°, the candidate location and the destination may be in two opposite directions of the origin location. In this condition, if the service requestor goes to the candidate location to get on board from the origin location, the service requestor may be farther away from the destination, which may cause a bad user experience for the service requestor.

The index determining module 440 may determine a convenience index based on the driving distance, the estimated driving time, or the angle between the first direction and the second direction. In some embodiments, each of the driving distance, the estimated driving time, and the angle may be indicated by a score. The shorter the driving distance is, the higher the score determined by the index determining module 440 for the driving distance is. The shorter the estimated driving time is, the higher the score determined by the index determining module 440 for the estimated driving time is. The smaller the angle is, the higher the score determined by the index determining module 440 for the angle is. In some embodiments, the driving distance, the estimated driving time, and the angle may correspond to a weight, respectively. The index determining module 440 may determine the convenience index by determining a weighted average of the driving distance, the estimated driving time, and the angle.

FIG. 5 is a flowchart illustrating an exemplary process 500 for recommending one or more pickup locations according to some embodiments of the present disclosure. In some embodiments, the process 500 may be implemented in the online on-demand transportation service system 100 illustrated in FIG. 1 . For example, the process 500 may be stored in the storage 150 and/or the storage device (e.g., the ROM 230, the RAM 240, the disk 270) as a form of instructions, and invoked and/or executed by the server 110 (e.g., the processing engine 112 in the server 110, the processor 220, or one or more modules in the processing engine 112 illustrated in FIG. 4 ). The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 500 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 500 as illustrated in FIG. 5 and described below is not intended to be limiting.

In 510, the processing engine 112 (e.g., the communication module 410) may receive a request or an intention for a transportation service from a service requestor. In some embodiments, the requestor terminal 130 of the service requestor (e.g., a passenger's smartphone) may install an application for requesting a transportation service. Through an interface of the application, the requestor terminal 130 may establish a connection and communicate with the online on-demand transportation service system 100. In some embodiments, the service requestor may input an origin location and a destination of the transportation service, and transmit out a request including the origin location and the destination of the transportation service to the processing engine 112 (e.g., the communication module 410) via, for example, the network 120. In some embodiments, the application may direct the requestor terminal 130 to constantly monitoring inputs from the service requestor and transmit the input to the processing engine 112 (e.g., the communication module 410). As a result, when the service requestor inputs part of the information of the transportation service, such as a destination, the processing engine 112 (e.g., the communication module 410) may receive enough information in real-time or substantially real-time to determine an intention of the service requestor. For example, when the service requestor inputs an origin location and a destination of the transportation service and before transmitting out the transportation service request to the processing engine 112 (e.g., the communication module 410), the processing engine 112 (e.g., the communication module 410) may receive and/or detect the origin location and the destination from the service requestor in real-time or substantially real-time, and determine that the service requestor intends to request the transportation service before receiving a request for the transportation service from the service requestor.

In some embodiments, the processing engine 112 (e.g., the communication module 410) may receive service signals from the requestor terminal 130. The service signals may include a first portion of structured data encoding the request or the intention for the transportation service, a second portion of the structured data encoding the origin location of the transportation service, and a third portion of the structured data encoding the destination of the transportation service.

In 520, the processing engine 112 (e.g., the service information determining module 420) may determine an origin location of the transportation service and a destination of the transportation service. In some embodiments, the request or the intention received by the processing engine 112 (e.g., the communication module 410) may include the origin location of the transportation service and/or the destination of the transportation service. The processing engine 112 (e.g., the service information determining module 420) may determine the origin location and the destination based on the request or the intention.

In 530, the processing engine 112 (e.g., the candidate location determining module 430) may obtain a plurality of predetermined locations. In some embodiments, the processing engine 112 (e.g., the candidate location determining module 430) may determine the plurality of predetermined locations in an area (e.g., the city of Beijing) in advance. The predetermined locations may be used to determine one or more pickup locations for a specific transportation service. The predetermined locations may be stored in the storage 150 or a storage medium (e.g., the disk 270, the ROM 230, or the RAM 240) of the processing engine 112. The processing engine 112 (e.g., the candidate location determining module 430) may access the storage 150 and/or the storage medium to obtain the predetermined locations.

In some embodiments, the processing engine 112 (e.g., the candidate location determining module 430) may transmit access signals to access the storage medium to read the plurality of predetermined locations. For example, the processing engine 112 (e.g., the candidate location determining module 430) may transmit the access signals to access the storage 150 to read the plurality of predetermined locations.

In 540, the processing engine 112 (e.g., the candidate location determining module 430) may determine one or more candidate locations based on the origin location and the plurality of predetermined locations. The processing engine 112 (e.g., the candidate location determining module 430) may select one or more predetermined locations that are within a predetermined distance (e.g., 500 meters) from the origin location as the candidate location(s). The predetermined distance may be a fixed distance or may be adjustable depending on different situations. For example, if the origin location is in a downtown area (e.g., the Xicheng district in Beijing), the predetermined distance may be relatively short (e.g., 400 meters) because the density of the predetermined locations there may be higher; whereas if the origin location is in a suburban area (e.g., the Changping district in Beijing), the predetermined distance may be relatively long (e.g., 1 kilometer) as the density of the predetermined locations there may be lower.

In 550, the processing engine 112 (e.g., the index determining module 440) may determine matching index values of the candidate locations based on the origin location and/or the destination. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine a matching index value for each candidate location. The matching index value of a candidate location may be the probability of the candidate location being a pickup location of the transportation service. The greater the matching index value is, the more suitable the candidate location is to be a pickup location for the transportation service. The matching index value may be in the form of a score, a percentage, a star level, or any suitable form.

In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the matching index value based on a walking cost, a convenience index, or a combination probability (e.g., as described in detail in connection with FIG. 6 ), or a combination thereof. The walking cost be a measurement associated with walking from the origin location to the candidate location. The convenience index may be a measurement associated with driving from the candidate location to the destination. The combination probability may be a probability of finding one or more shareable transportation services in the candidate location to combine with the transportation service.

In 560, the processing engine 112 (e.g., the pickup location determining module 450) may determine one or more pickup locations based on the matching index values. In some embodiments, the processing engine 112 (e.g., the pickup location determining module 450) may rank the matching index values in ascending order or descending order. In some embodiments, the processing engine 112 (e.g., the pickup location determining module 450) may determine one pickup location from the candidate locations based on the matching index values. For example, the processing engine 112 (e.g., the pickup location determining module 450) may determine the candidate location having the greatest matching index value as the pickup location of the transportation service. In some embodiments, the processing engine 112 (e.g., the pickup location determining module 450) may determine more than one pickup location. For example, the processing engine 112 (e.g., the pickup location determining module 450) may determine the top three candidate locations as the pickup locations based on the matching index values.

In 570, the processing engine 112 (e.g., the communication module 410) may transmit the one or more pickup locations to the service requestor and/or the service provider. In some embodiments, if the processing engine 112 (e.g., the pickup location determining module 450) determines one pickup location, the processing engine 112 (e.g., the communication module 410) may transmit the pickup location to the service requestor. After receiving the pickup location, the application installed in the requestor terminal 130 of the service requestor (e.g., a smartphone of a passenger) may provide an interface to notify the passenger of the pickup location in the way of text, sound, picture, video, or the like, or any combination thereof. For example, the interface of the application may display a text showing “Please get on board at East Gate of Renmin University.” Alternatively or additionally, the processing engine 112 (e.g., the communication module 410) may transmit the pickup location to a service provider that provides the transportation service to the service requestor.

In some embodiments, if the processing engine 112 (e.g., the pickup location determining module 450) determines more than one pickup location, the processing engine 112 (e.g., the communication module 410) may transmit the more than one pickup location to the service requestor. The service requestor may select one from the more than one pickup location. After receiving the more than one pickup location, the application installed in the requestor terminal 130 of the service requestor (e.g., a smartphone of a passenger) may provide an interface to notify the passenger of the more than one pickup location in a way of text, sound, picture, video, or the like, or any combination thereof. For example, the interface of the application may display a list of the more than one pickup location. In the list, the more than one pickup locations may be arranged in ascending order, descending order, or random order. The passenger may select one pickup location from the list. After receiving the instruction of selecting one from the one or more pickup locations, the requestor terminal 130 may transmit the selected pickup location to the processing engine 112. Alternatively or additionally, after receiving the selected pickup location from the requestor terminal 130, the processing engine 112 (e.g., the communication module 410) may transmit the selected pickup location to the service provider who provides the transportation service to the service requestor.

In some embodiments, the processing engine 112 (e.g., the communication module 410) may transmit location signals encoding the one or more pickup locations to the requestor terminal 130.

In some embodiments, the processing engine 112 may determine whether the carpool transportation service is available for the area in which the origin location locates. The processing engine 112 (e.g., the pickup location determining module 450) may determine one or more pickup locations for the service requestor in response to the determination that the carpool transportation service is available in the area. In response to the determination that the carpool transportation service is available for the area that the origin location locates in, the processing engine 112 (e.g., the communication module 410) may transmit a message to the requestor terminal 130 to notify the service requestor of the determination.

FIG. 6 is a flowchart illustrating an exemplary process for determining a matching index value for a candidate location according to some embodiments of the present disclosure. In some embodiments, the process 600 may be implemented in the online on-demand transportation service system 100 illustrated in FIG. 1 . For example, the process 600 may be stored in the storage 150 and/or the storage device (e.g., the ROM 230, the RAM 240) as a form of instructions, and invoked and/or executed by the server 110 (e.g., the processing engine 112 in the server 110, the processor 220, or one or more modules in the processing engine 112 illustrated in FIG. 4 ). The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 600 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 600 as illustrated in FIG. 6 and described below is not intended to be limiting. In some embodiments, step 550 illustrated in FIG. 5 may be performed based on the process 600. For one candidate location, the processing engine 112 may perform the process 600 to determine a matching index value. The processing engine 112 may determine a matching index value for each candidate location one by one or simultaneously.

In 610, the processing engine 112 (e.g., the index determining module 440) may determine a walking cost of a candidate location. The walking cost may be a measurement associated with walking from the origin location to the candidate location. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine a score of the walking cost. The greater the score of the walking cost is, the better the user experience of walking from the origin location to the candidate location is. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the walking cost based on the walking distance between the origin location and the candidate location, the estimated walking time between the origin location and the candidate location, the direct distance between the origin location and the candidate location, or the number of historical requests of which pickup locations are the candidate location (e.g., as will be described in detail in connection with FIG. 7 ), or a combination thereof.

In 620, the processing engine 112 (e.g., the index determining module 440) may determine a convenience index of the candidate location. The convenience index may be a measurement associated with driving from the candidate location to the destination by the service provider. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine a score of the convenience index. The greater the score of the convenience index is, the better the user experience of driving from the candidate location to the destination is. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the convenience index based on a driving distance between the candidate location and the destination, the estimated driving time between the candidate location and the destination, an angle between a direction from the origin location to the candidate location, a direction from the origin location to the destination (e.g., as will be described in detail in connection with FIG. 8 ), or a combination thereof.

In 630, the processing engine 112 (e.g., the index determining module 440) may determine a combination probability of the candidate location. The combination probability may be a probability of finding one or more shareable transportation services in the candidate location to combine with the transportation service. A shareable transportation service may satisfy at least three conditions: the pickup location of the shareable transportation service is the candidate location; a service requestor of the sharable transportation service has not departed from the candidate location (e.g., the service requestor of the shareable transportation service is on the way of going to the candidate location, or the service requestor of the shareable transportation service is waiting for a driver at the candidate location); the destination of the shareable transportation is related to the destination of the transportation service (e.g., the destination of the shareable transportation is on a driving route of the transportation service, the destination of the transportation service is on a driving route of the shareable transportation service, or the destination of the shareable transportation is within a distance from the destination of the transportation service). In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the combination probability based on the number of shareable transportation services in the candidate location and a carpool capacity. The carpool capacity may be the maximum number of passengers in a vehicle at the same time. The carpool capacity may be a fixed value or may be adjustable depending on different situations. For example, in rush hours (e.g., 7:00 am-9:00 am), the carpool capacity may be relatively great (e.g., 4 passengers) because the demand for service providers may exceed the supply; whereas in other hours (e.g., 10:00 am-12:00 am), the carpool capacity may be relatively small (e.g., 2 passengers) as the supply of service providers may exceed the demand or there may be a balance between demand and supply of service providers.

For the purpose of illustration, the determination of the combination probability may be described using an example below. It should be noted that the determination of the combination probability described below is merely provided for illustration and not intended to limit the scope of the present disclosure. For example, suppose that the number of passengers of a transportation service may be 1. The processing engine 112 (e.g., the index determining module 440) may determine that the carpool capacity is 2 passengers. The processing engine 112 (e.g., the index determining module 440) may determine three candidate locations (e.g., location A, location B, and location C). The processing engine 112 (e.g., the index determining module 440) may determine that there is no shareable transportation service in location A, there is 1 shareable transportation service in location B, and there are 2 shareable transportation services in location A. The processing engine 112 (e.g., the index determining module 440) may determine that the combination probability of location B is the greatest and the combination probability of location A is the least.

In some embodiments, for a condition that there is no shareable transportation service in all of the candidate locations, the processing engine 112 (e.g., the index determining module 440) may determine the combination probability based on historical requests. For example, the processing engine 112 (e.g., the index determining module 440) may access the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240) to obtain the number of historical shareable transportation services associated with the time point when the processing engine 112 (e.g., the communication module 410) receives the request or the intention for the transportation service from the service requestor and the candidate location. The historical shareable transportation service may satisfy at least three conditions: the pickup location of the historical shareable transportation service is the candidate location; the historical shareable transportation service ended (e.g., the historical shareable transportation service may be cancelled or finished); the destination of the historical shareable transportation is related to the destination of the transportation service (e.g., the destination of the historical shareable transportation is on a driving route of the transportation service, the destination of the transportation service is on a driving route of the historical shareable transportation service, or the destination of the historical shareable transportation is within a distance from the destination of the transportation service). For example, the processing engine 112 (e.g., the communication module 410) receives the request or the intention for the transportation service from the service requestor at 9:10 am. The processing engine 112 (e.g., the index determining module 440) may obtain historical shareable transportation services of which the request times are in a range from, for example, 9:05 am-9:15 am of every one of the past 5 days.

In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine a score of the combination probability. The greater the score of the combination probability is, the greater the combination probability is, and the more possible it is to find a shareable transportation service in the candidate location to combine with the transportation service.

In 640, the processing engine 112 (e.g., the index determining module 440) may determine a matching index value based on the walking cost, the convenience index, and the combination probability. The processing engine 112 (e.g., the index determining module 440) may determine weights for the walking cost, the convenience index, and the combination probability. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the matching index value by determining a weighted average of the walking cost, the convenience index, and the combination probability. For example, the processing engine 112 (e.g., the index determining module 440) may determine the matching index value based on Equation (1) below: M=W _(walk) S _(walk) +W _(drive) S _(drive) +W _(comb) S _(comb)  (1), wherein M refers to the score of the matching index value, S_(walk) refers to the score of the walking cost, S_(drive) refers to the score of the convenience index, S_(comb) refers to the score of the combination probability, W_(walk) refers to the weight of the walking cost, W_(drive) refers to the weight of the convenience index, and W_(comb) refers to the weight of the combination probability.

In some embodiment, the processing engine 112 (e.g., the index determining module 440) may perform step 610, step 620, and step 630 in any order. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may perform step 610, step 620, and step 630 simultaneously.

FIG. 7 is a flowchart illustrating an exemplary process for determining a walking cost for a candidate location according to some embodiments of the present disclosure. In some embodiments, the process 700 may be implemented in the online on-demand transportation service system 100 illustrated in FIG. 1 . For example, the process 700 may be stored in the storage 150 and/or the storage device (e.g., the ROM 230, the RAM 240) as a form of instructions, and invoked and/or executed by the server 110 (e.g., the processing engine 112 in the server 110, the processor 220, or one or more modules in the processing engine 112 illustrated in FIG. 4 ). The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 700 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 700 as illustrated in FIG. 7 and described below is not intended to be limiting. In some embodiments, step 610 illustrated in FIG. 6 may be performed based on the process 700.

In 710, the processing engine 112 (e.g., the index determining module 440) may determine a walking route from the origin location to the candidate location.

In 720, the processing engine 112 (e.g., the index determining module 440) may determine a walking distance based on the walking route. In some embodiments, the walking distance may be the length of the walking route.

In 730, the processing engine 112 (e.g., the index determining module 440) may determine an estimated walking time based on the walking route. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the estimated walking time based on the walking distance, walking speed, condition of the walking route, or the like, or any combination thereof.

In some embodiments, the walking speed may be a fixed speed (e.g., 4 km/h) or may be adjustable depending on different situations. For example, for passengers over 60 years old, the walking speed may be relatively slow (e.g., 3 km/h); for passengers from 20 to 60 years old, the walking speed may be relatively fast (e.g., 4.5 km/h). In some embodiments, the service requestor may input his/her basic information (e.g., a name, a phone number, an age) when the service requestor first uses the application installed in the requestor terminal 130 (e.g., a smartphone of the service requestor) to request a transportation service. The requestor terminal 130 may transmit the basic information to the processing engine 112 (e.g., the index determining module 440). After receiving the basic information, the server 110 may store the basic information in the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240). When determining the walking speed, the processing engine 112 (e.g., the index determining module 440) may access the storage 150 or the storage medium to obtain the basic information of the service requestor and determine the walking speed based on the basic information. In some embodiments, the requestor terminal 130 may determine the walking speed of the service requestor using the positioning technology in the requestor terminal 130 and transmit the walking speed to the processing engine 112 (e.g., the index determining module 440) in real time. The condition of the walking route may include the weather, information on events (e.g., a traffic accident, a concert), or the like, or any combination thereof.

In 740, the processing engine 112 (e.g., the index determining module 440) may determine a direct distance from the origin location to the candidate location.

In 750, the processing engine 112 (e.g., the index determining module 440) may determine the number of historical requests associated with the candidate location. The number of requests associated with the candidate location may refer to the number of historical requests in a time period (e.g., in the past one month from the time point when the processing engine 112 receives the service request or the intention of the transportation service) of which the pickup locations are the candidate location.

In 760, the processing engine 112 (e.g., the index determining module 440) may determine a walking cost based on the walking distance, the estimated walking time, the direct distance or the quantity of historical requests associated with the candidate location. In some embodiments, the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location may correspond to a score, respectively. The shorter the walking distance is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the walking distance is. The shorter the estimated walking time is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the estimated walking time is. The shorter the direct distance is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the direct distance is. The greater the number of historical requests associated with the candidate location is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the number of historical requests associated with the candidate location is. In some embodiments, the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location may correspond to a weight, respectively. The processing engine 112 (e.g., the index determining module 440) may determine the walking cost by determining a weighted average of the walking distance, the estimated walking time, the direct distance, and the number of historical requests associated with the candidate location. For example, the processing engine 112 (e.g., the index determining module 440) may determine the walking cost based on Equation (2) below: S _(walk) =W _(wd) S _(wd) +W _(wt) S _(wt) +W _(ld) S _(ld) +W _(h) S _(h)  (2), wherein S_(walk) refers to the score of the walking cost, S_(wd) refers to the score of the walking distance, S_(wt) refers to the score of the estimated walking time, S_(ld) refers to the score of the direct distance, S_(h) refers to the score of the quantity of historical requests associated with the candidate location, W_(wd) refers to the weight of the walking distance, W_(wt) refers to the weight of the estimated walking time, W_(ld) refers to the weight of the direct distance, and W_(h) refers to the weight of the quantity of historical requests associated with the candidate location.

In some embodiment, the processing engine 112 (e.g., the index determining module 440) may perform steps 720-750 in any order. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may perform steps 720-750 simultaneously.

FIG. 8 is a flowchart illustrating an exemplary process for determining a convenience index for a candidate location according to some embodiments of the present disclosure. In some embodiments, the process 800 may be implemented in the online on-demand transportation service system 100 illustrated in FIG. 1 . For example, the process 800 may be stored in the storage 150 and/or the storage device (e.g., the ROM 230, the RAM 240) as a form of instructions, and invoked and/or executed by the server 110 (e.g., the processing engine 112 in the server 110, the processor 220, or one or more modules in the processing engine 112 illustrated in FIG. 4 ). The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 800 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 800 as illustrated in FIG. 8 and described below is not intended to be limiting. In some embodiments, step 620 illustrated in FIG. 6 may be performed based on the process 800.

In 810, the processing engine 112 (e.g., the index determining module 440) may determine a driving route from the candidate location to the destination.

In 820, the processing engine 112 (e.g., the index determining module 440) may determine a driving distance based on the driving route. The driving distance may refer to the length of the driving route.

In 830, the processing engine 112 (e.g., the index determining module 440) may determine an estimated driving time based on the driving route. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the estimated driving time based on the driving distance, driving speed, the condition of the driving route, or the like, or any combination thereof.

In some embodiments, the driving speed may be a fixed speed (e.g., 40 km/h), or may be adjustable depending on different situations. For example, for a high configuration vehicle (e.g., a BMW™), the driving speed may be relatively great (e.g., 45 km/h); for a low configuration vehicle (e.g., an Alto™), the driving speed may be relatively small (e.g., 35 km/h).

For a condition that the processing engine 112 has allocated a service provider to the service requester, the processing engine 112 (e.g., the index determining module 440) may determine the driving speed based on the vehicle of the service provider. In some embodiments, the service provider may input his/her basic information (e.g., a name, a phone number, a vehicle type, a vehicle plate number) when the service provider first uses the application installed in the provider terminal 140 (e.g., a smartphone of the service provider) to provide a transportation service. The provider terminal 140 may transmit the basic information of the service provider to the processing engine 112. After receiving the basic information of the service provider, the processing engine 112 may store the basic information in the storage 150 and/or the storage medium (e.g., the ROM 230, the RAM 240). When determining the driving speed, the processing engine 112 (e.g., the index determining module 440) may access the storage 150 or the storage medium to obtain the basic information of the service provider and determine the driving speed based on the basic information of the service provider. Alternatively or additionally, the provider terminal 140 may determine the driving speed of the vehicle using the positioning technology in the provider terminal 140 and transmit the driving speed to the processing engine 112 (e.g., the index determining module 440) in real time.

For a condition that the processing engine 112 has not allocated a service provider to the service requestor, the processing engine 112 (e.g., the index determining module 440) may determine the driving speed based on the default of the processing engine 112 (e.g., 40 km/h).

The condition of the driving route may include the number of vehicles on the driving route, the weather, information on events (e.g., a traffic accident, a concert), or the like, or any combination thereof.

In 840, the processing engine 112 (e.g., the index determining module 440) may determine the first direction from the origin location to the destination and a second direction from the origin location to the candidate location.

In 850, the processing engine 112 (e.g., the index determining module 440) may determine an angle between the first direction and the second direction. In some embodiments, the processing engine 112 (e.g., the index determining module 440) may determine the angle between the first direction and the second direction in order to determine whether the candidate location and the destination are in two opposite directions of the origin location. If the processing engine 112 (e.g., the index determining module 440) determines that the angle is 0°, the candidate location and the destination may be in a same direction of the origin location. If the processing engine 112 (e.g., the index determining module 440) determines that the angle is 180°, the candidate location and the destination may be in two opposite directions of the origin location. In this condition, if the service requestor goes to the candidate location to get on board from the origin location, the service requestor may be farther away from the destination, which may cause a bad user experience for the service requestor.

In 860, the processing engine 112 (e.g., the index determining module 440) may determine a convenience index based on the driving distance, the estimated driving time, or the angle between the first direction and the second direction. In some embodiments, each of the driving distance, the estimated driving time, and the angle may be indicated by a score. The shorter the driving distance is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the driving distance is. The shorter the estimated driving time is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the estimated driving time is. The smaller the angle is, the higher the score determined by the processing engine 112 (e.g., the index determining module 440) for the angle is. In some embodiments, the driving distance, the estimated driving time, and the angle may correspond to a weight, respectively. The processing engine 112 (e.g., the index determining module 440) may determine the convenience index by determining a weighted average of the driving distance, the estimated driving time, and the angle. For example, the processing engine 112 (e.g., the index determining module 440) may determine the convenience index based on Equation (3) below: S _(drive) =W _(dd) S _(dd) +W _(dt) S _(dt) +W _(angle) S _(angle)  (3), wherein S_(drive) refers to the score of the convenience index, S_(dd) refers to the score of the driving distance, S_(dt) refers to the score of the estimated driving time, S_(angle) refers to the score of the angle, W_(dd) refers to the weight of the driving distance, W_(dt) refers to the weight of the estimated driving time, and W_(angle) refers to the weight of the angle.
